Needless to say, I lost quickly, but while looking at the game I got to messing around with 5.h4 and discovered that in his book Starting Out: Dutch Defense Neil McDonald included the interesting move h4 against the Leningrad Dutch. That lead me to uncover the following game between Daniel Gurevich and Torbjorn Hansen. There's a bunch of players named Gurevich: Ilya, Mikhail, Dmitry and Vladimir, but this game was won by IM Daniel Gurevich, a protege of GM Roman Dzindzichashvili.
Gurevich played the provocative 4.h4 against the Dutch and the complications that ensued were great, but he kept things under control despite the dizzying tactics that followed. Hansen's 28...Rf2 set a nasty trap that Gurevich avoided.
